History of the Peloponnesian War

"For though in pleas of covenants with our confederates when, in our own city we have allowed them trial by laws equal both to them and us, the judgment hath been given against us, we have then nevertheless been reputed contentious.

None of them considering that others, who in other places have dominion and are toward their subject states less moderate than we, yet are never upbraided for it.

For they that have the power to compel need not at all to go to law. And yet these men having been used to converse with us upon equal terms, if they lose anything which they think they should not, either by sentence or by the power of our government, they are not thankful for the much they retain, but take in worse part the little they forego than if at first, laying law aside, we had openly taken their goods by violence. For in this kind also they themselves cannot deny but the weaker must give way to the stronger.

And men, it seems, are more passionate for injustice than for violence. For that, coming as from an equal, seemeth rapine, and the other, because from one stronger, but necessity.
